JOHN WEST, OF MINNEAPOLIS, MINNESOTA.

IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 160,133, dated February23, 1875; application filed December 15, 1874.

To all whom yit may concern:

Be it known that I, JOHN VVEsT, a resident of the city of Minneapolis,county of Hennepin and State of Minnesota, have invented certain new anduseful Improvements in Garv Coupling Device, of which the following is aclear, full, and exact description, reference being had to theaccompanying drawings, which are a part of this speciication.

Figure 1 is a side view, and Fig. 2 a top View.

The letters of reference are used in both gures in the designation ofidentical parts.

The following description will enable others skilled in the art to makeand use my invention.

The piece a is formed in the shape shown in Fig. l, and works in theordinary draw-head. The upper and outer projecting part is rounded onits outer face, so as to permit the clevislink b to slide over and hookin its inner face, which may be slightly concave, so that it may thebetter retain the link b. The links b b are used upon each bumper, and,when in place over the projecting hooks, give a double security, itmaking no difference which link attempts to gain the position irst, theother falling in proper position. The lever-rods g, by the aid of theirattached cams c and c, are used to uncouple the links.

In Fig. 2 are shown the trips h h, fixed to the inner portion of thehooked piece a, and used to trip the clevis-link b b when the drawheadsmeet.

The object of my invention is to produce an automatic car-coupler withattached devices for uncoupling, so as to avoid the necessity forpersons entering between the cars to either couple or uncouple.

Having th us described my invention, what I claim, and wish to secure byLetters Patent,

The independently-acting piece a, in combination with the clevis-link b,uncoupling devices g e, and trips h, substantially as and for thepurpose specied.

JOHN WEST.
